A pioneer of modern music, Riley's all night performances of his work were ground breaking experimental events and influenced composers such as Philip Glass. Released as an album in 1969, A Rainbow in Curved Air; brought Riley to a wider rock audience. The British band Curved Air took their name from this work and Pete Townshend of The Who was inspired by Riley's music to create the seminal songs Baba O' Riley and Won't Get Fooled Again. A Rainbow in Curved Air remains a highly influential creation.
